Potassium Dodecyl Sulfate
Time:2012-09-07 15:50:02,Count:0
Appearance    (1), white to slightly yellow crystals, flakes, or powder; (2), liquid.
Odor    faint characteristic odor.
Solubility    soluble in water.Aqueous solution is colorless transparent to translucent, transparency influenced greatly by concentration and temperature. Generally, as the concentration increases, the opacity will increases; as the temperature decreases, the opacity will also increases.
Hygroscopicity    hygroscopic. Powdery potassium dodecyl sulfate cakes easily, but the cake strength is not high.
Physical - chemical properties
Flash point, °C
> 90
Stability    stable in alkali, weak acid and hard water; unstable in strong acid, hydrolyzed, reduced to alcohol.
Risk    Solid form: flammable material; irritation, moderate irritation to skin, eye, respiratory. Harmful products of combustion are CO, CO2 and so on. Contact with strong oxidants, can cause to burn.
GHS (Rev.6) label:  
Liquid form: irritation, moderate irritation to skin, eye.
GHS (Rev.6) label:
Animal toxicity    Reference [1]: The metabolic fate of potassium dodecyl sulphate was studied in rats. Studies have shown that: by intraperitoneal, oral and intravenous administration, the urine within 12h, has approx. 17% inorganic sulfate metabolites, meanwhile, there is an ester in metabolites: butyric acid 4-sulphate.
Ecology    may be hazardous to environment. Water body should be given special attention.
Biodegradability    biodegradable.
Characteristics    excellent foaming, cleansing, emulsifying, wetting, permeating, dispersing, solubilizing, antistatic abilities. Resistant to hard water.
Note    (1), Avoid using in children cleaning products, such as shower gels, shampoo, skin care products.
